The Leaning Tower of Pisa was built in August 1173 as a separate bell tower for the Cathedral of Pisa, Italy, on the Miracle Square north of Pisa City, Tuscany Province, Italy. A large lawn of the Miracle Square is strewn with a collection of religious buildings, the cathedral (built in 1063-13th century), the baptismal church (built in 1153-14th century), the bell tower (the Leaning Tower of Pisa) and the cemetery (built in 1174), all of which are made of milky marble. The tower is located behind the cathedral of Pisa, which is relatively independent but has a unified Roman architecture.
